Food colors are organic compounds that are soluble in water, butcan also bind to various things. One thing they bind to is silicagel, SiO2. Consider the following two experiments: Anequilibrium is established between some silica gel, water, and bluefood color so that both the water and the silica gel have anoticeable amount of blue.
Control: One portion of the initial solution is filtered and thecolor intensity in the water and on the solid silica gel aremeasured.
Experiment A: A second portion of the initial solution has thevolume doubled by adding water. The re-equilibrated mixture isagain filtered and the color intensities determined.
Experiment B: A third portion of the initial solution has theamount of silica gel it contains doubled by adding fresh silicagel. The re-equilibrated mixture is again filtered and the colorintensities determined.
Which of the following statements is true?
A) Experiment A: The intensity of both colors that weremeasured decreases.
Experiment B: The intensity of both colorsthat were measured decreases.
B) Experiment A: The intensity of both colors that weremeasured decreases.
Experiment B: The intensity of the colorin the water stays the same, but the intensity of the color on thesilica gel decreases.
C) Experiment A: The intensity of the color in the waterdecreases, but the intensity of the color on the silica gel staysthe same.
Experiment B: The intensity of bothcolors that were measured decreases.
D) Experiment A: The intensity of the color in the waterdecreases, but the intensity of the color on the silica gel staysthe same.
Experiment B: The intensity of the colorin the water stays the same, but the intensity of the color on thesilica gel decreases
